Embodiment 1
[0023] The method of this relay protection operation checking, comprises the following steps:
[0024] First, establish a relay protection operation rule library, use the protection operation rule definition tool, take the parameters of the protection device as the rule configuration object, and define the operation mode of the relevant protection device in the primary equipment operation state. Fixed value area code, fixed value, binary input state;
[0025] Secondly, the protection operation verification service process obtains the real-time operation information of the power grid from the basic platform of the smart grid dispatching technical support system, obtains the real-time operation information of the relay protection from the protection information management master station, and executes the following tasks cyclically:
[0026] For each primary device object, call the primary device operation state discrimination interface, search out the matching protection operati...

The invention discloses a method for checking the operation of relay protection. The parameters of the protection device, such as the input and withdrawal status of the pressure plate, the fixed value area code, the fixed value, and the binary input status, are used as the rule configuration objects, and the relevant protection is defined in the primary equipment operation state. According to the operation mode of the device, establish a relay protection operation rule library, obtain real-time operation information of the power grid from the basic platform of the smart grid dispatching technical support system, obtain real-time operation information of relay protection from the protection information management master station, and use the protection operation rule library to judge Whether the operation mode of the protective device meets the requirements of the relevant operating rules. If the requirements are not met, relevant warning prompts will be given. The invention can effectively solve the problem that the operation mode of the relay protection cannot meet the operation requirements of the power grid due to incorrect on-site protection operation, which causes potential safety hazards in the operation of the power grid.
Description
technical field [0001] The invention relates to a relay protection operation check technology of a power system smart grid dispatching technical support system, in particular to a relay protection operation check method. Background technique [0002] Relay protection equipment is an important equipment to ensure the safe and stable operation of the power grid, and it is the first line of defense of the power system. The fixed value of the relay protection equipment and the switching status of the pressure plate are important parameters for the logic judgment of the relay protection, which determine the correctness of the protection action and also affect the performance of the protection. With the continuous expansion of the grid scale and the continuous increase of grid transformation projects, the operation of grid equipment is becoming more and more frequent, resulting in frequent changes in the operation mode of the grid. When the power grid mode changes, it is necessar...
